Safety & Warnings
Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes be performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltages pose an even greater threat because such voltage can more easily produce a lethal current. Your normal work habits should include all accepted practices to prevent contact with exposed high voltage, and to steer current away from your heart in case of accidental contact with a high voltage. You will significantly reduce the risk factor if you know and observe the following safety precautions:
1. Don’t expose high voltage needlessly. Remove housings and covers only when necessary. Turn off equipment while making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power.
2. If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. However, remember that high voltage may appear at unexpected points in defective equipment.
3. Use an insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface on which to place equipment: and make certain such surfaces are not damp or wet.
4. Use the time proven “one hand in the pocket” technique while handling an instrument probe. Be particularly careful to avoid contacting a nearby metal object that could provide a good ground return path.
5. When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuits such as the on-off switch, fuses, power transformer, etc. any time the equipment is connected to an ac outlet, even if the equipment is turned off.

Always observe polarity when measuring DC voltage or current. Use the data hold feature to freeze readings for easier recording. Turn off the device after use to conserve battery life.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or no display, check the battery status and replace if necessary. Inspect test leads for damage or loose connections. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. If the device fails to operate correctly after these checks, consult the service center authorized by Bk-precision.
Safety Reminder
Always observe proper safety precautions when working with electrical equipment. Do not exceed the specified input limits of the multimeter to prevent damage or injury. Avoid measuring high voltages or currents without proper protective equipment. Disconnect power from circuits before testing resistance or continuity. Keep the device away from water and flammable materials to ensure safe operation.
